I'd say that will be just fine, your circumference will be 1.5% higher, and you'll have 5mm more ground clearance. That is well within the normal 3% tolerance assumed for tire sizes. The width won't be an issue, people are putting much wider tires on these cars without trouble.
Do the 245s fit ok on the stock rims? How do they look?it will work, it may cost you a little range. Typically the rule is 3% variance is acceptable. Because it's an EV I personally have been trying to keep it closer when I customized it. Hard to say no though when you own the tires.
And I can verify the 235 width will work I put 245/50/19 on mine
I used aftermarket rims but yes they should fit the factory rims. I had Vredestein Hypertrac tires and the spec in them is they will fit 7-8.5" rims. You can always look on tire rack they post that information under specs. Attached is the specs section from the Conti dws
Mounted and ran them last winter from Jan to April (lots of snow in April last year). Ran just fine. Will be mounting them again around Thanksgiving.
No.
